Geophysical Multifunction Transmitter SKAT IV
Transmitter SGD-EGC200 SKAT IV is intended for the producing of bi-polar rectangular signals of specified frequency, amplitude and duty cycle. Its user-friendly interface alongside with small dimensions make it the best solution for wide range of geotechnical and mining geophysical surveys.
The maximum output power of the SKAT IV transmitter (200 W) provides the investigation depth up to 100-200 m. Built-in LED display together with keypad makes survey process very convenient and flexible.
Pre-set signal frequencies are compatible with many types of geophysical recorders. Stabilized signal form and amplitude allows IP measurements both in frequency and time domains.
Transmitter SKAT IV is used to perform surveys:
- Resistivity methods
- Induced polarication
- Frequency sounding
There are 2 variants of delivery sets — standard and advanced. The difference is that advanced set includes unloading with battery and the charger for battery.
